Characteristics
Linux Libertine is a proportional serif typeface inspired by 19th century book type and is intended as a replacement for the Times font family.
The typeface has five styles: regular, bold, italic, bold italic, and small capitals, all of which are available in TrueType and OpenType format, as well as in source code. The OpenType version allows automatic positioning and substitution, including true fractions, ligatures and kerning.
There is also a complementary organic sans-serif face, Linux Biolinum.
